A stunning Valentine's view of a nebula contains hidden depths of starbirth and the violent deaths of massive stars.

Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. These particular stars, called pulsars, reside together in globular cluster Terzan 5, a crowded home for hundreds of thousands of different types of stars.

A young star that astronomers have studied for decades has been found to be part of a duo, encircled by a disk of material within which planets may have just...

The ALMA telescope spotted a molecular gas outflow coming from a black hole-powered, 13-billion-year-old quasar, explaining why some galaxies stop forming...

Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the universe was less than a billion years old.

A bizarre object discovered by the James Webb Space Telescope may be a pair of 'rogue' planets ― but a new study finds they are emitting radio signals rarely seen from other worlds.

Researchers using data from NASA's Imaging X-ray Polarimetry Explorer to study a microquasar – a distant black hole stripping a companion star of material – have published new findings about how cosmic-ray particles streaming away from the microquasar may be accelerated to nearly the speed of light.

New research suggests that the Green Monster -- a curious structure first spotted in Webb data in April 2023 -- came from that blast wave slamming into material surrounding the Cassiopeia A supernova remnant.

Superintelligences might reveal themselves through the technosignatures of their cosmic engineering projects.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.

Observing a distant quasar powered by a supermassive black hole could help better constrain the properties of this mysterious form of matter.

Scientists' recent detection of low-frequency gravitational waves may shed light on what's causing a constant rumble of ripples in the very fabric of space and time.

The largest storm in the solar system, a 10,000-mile-wide anticyclone called the Great Red Spot, has decorated Jupiter's surface for hundreds of years.

Graphene has long been put forward as a wonder material. Undeniably, it has astounding properties—stronger than steel, a better electrical conductor than copper, and lighter than almost anything else with similar properties. And while it's been partially adopted into space-faring technologies, many use cases remain where a pure form of the material could dramatically benefit the space industry.

The most important feature of a black hole is that it has an event horizon: a region of space where the gravitational field is so strong that nothing, not even light, can escape from it. How, then…

Astronomers are now seeking to pinpoint the origins of an exciting new form of gravitational waves that was announced earlier this year

When it comes to the story of how our Solar System came to be, some pieces fall into place more readily than others. Most stellar systems form with a protoplanetary disk around them, yielding planets…

Astronomers want to confirm this unprecedented find.

An international team of astronomers has detected a faint signal of gravitational waves reverberating through the universe. By using dead stars as a giant network of gravitational wave detectors, the collaboration—called NANOGrav—was able to measure a low-frequency hum from a chorus of ripples of spacetime.

A 15-year study has revealed the cosmic background noise of gravitational waves echoing across the universe for the first time.
